If it’s eBay it’s basically guaranteed that you can return. Even if the seller says otherwise. Also like just say that you can’t boot Windows, you’re not wrong.

@K4sum1 Ohh I’m not getting mine from eBay, I purchase goods from abroad (mainly from Japan) with an online serice., thus it’s virtually impossible to do returns, even if the option is there, the delivery costs would be high, almost defeating purpose of the purchase itself 
Odd scenario. I did some research and found this.
B550-F, similarish board idk. Confirmed working for at least one person.

I looked up X570-F and the similar X570-E. I haven’t seen it directly confirmed, but I would assume I would see posts if it didn’t work for them. You can also try double checking and asking.
Considering there is no broken ASUS board that is known, more likely than not you’re fine. I probably would’ve gotten a X570-E/F if I hadn’t decided to get the Creation instead.

Hello. I am trying to install Win 7 on my ASUS PRIME x570-P motherboard and a Ryzen 7 5700x CPU. I have gotten past the first challenge of the installation by using a modded Win 7 ISO that has USB drivers installed so I can move my mouse and use my keyboard during installation. My new problem is when the system boots I get to the screen saying “Starting Windows”. I have Launch CSM Enabled in BIOS, Boot Driver Control on UEFI and Legacy. Resize BAR disabled.
Please tell me if you need more information. I will be happy to reply. Thanks and have a nice day :]
@Thorbjorn
Welcome to the Win-Raid Forum!
Since the lack of matching original USB drivers is not the only problem to get Win7 properly installed onto systems with an AMD X570 Chipset and a Ryzen 5000 Series CPU, I have moved your post into this already existing thread about the related topic.
Good luck!

@K4sum1 Greatest apologies for my late reply…forgiveness please! 
But thanks every much for that post/link and yes you are right, it’s not “directly” confirmed that I myself have seen word that people have the this board and the only problem they’ve come across really was just USB issues.
Back on this matter and on your previous post where’ve linked the motherboard recommendations, MSI X570 Creation is listed to be working with 2700X and 5950X. May I ask, is this still the case with the latest BIOS update; version 7C36v1N?
Don’t mind, I already forgot about the posts here.
I’m still running 7C36v1I from 2022. I don’t want to upgrade since everything just works, I would need to redo my PBO settings and whatever. I would also get the BIOS security patches that would slow down my PC. There’s also the risk of bricking my PC. I don’t think I will be trying v1N.

@K4sum1 Thanks for getting back to me here and I hope this jogs your memory!
Interesting to hear that you’re still on an older BIOS, it would be really interesting to know if the latest version still retain compatibility for Windows 7 
I ask well because I’m planning to go where not many has gone, albeit taking the microcode from a BIOS of the MSI X570 Creation and injecting it to the latest BIOS file of the Asrock X570 Pro4 
I don’t think microcode is an issue here.
What do you think the issue is then perhaps?
Not sure, maybe the BIOS itself or ACPI tables or something idk. Microcode should be the same between all.
@K4sum1 I actually asked a question regarding that precise matter and it was addressed by our very own @Fernando
It seems that each motherboard manufacturer places it’s own microcode.
AMD makes the microcode, I don’t think it would differ between manufacturers. However I also have no idea if this is correct as I haven’t looked into it.
@K4sum1 This is now pretty conficting, you believe the microcode wouldn’t differ between manufacturers, whereas @Fernando states that they do. 
@Fernando May I ask, do you know if there is any proof or evidence that indicates microcode differing from different manufacturers by any chance?? 
He might be right as he does BIOS stuff and I don’t. I’m just deducing that unless AMD provides board manufacturers source code (unlikely) then it is likely the same.
Hello everyone…long time!
Hope you’re all doing well!
I can’t begin to tell how how depessing it has been for me as I went into a big decline in trying to make my x570 Pro4 to work.
Long story short, I got kind of obsessed with the idea that it had to do with Microcodes in the BIOS. So I began learning how to extract and inject microcodes from different motherboards and injecting them into the Pro4’s current bios version. None of them worked.
The final straw is when I decided to use a server BIOS from Asrock and took its microcode and placed it in mine.
Whilst that didn’t work, this is where it gets muddy.
At the same time of doing this, I was in the process for the 100th time exchanging CPUs, and due to a combination of being tired and frustrated, removing the CPU cooler became surprisingly challenging, I made some wiggle and aggressive movements that I somehow slipped my Ryzen 5950x off the socket.
A couple rows of bent pins.
Tried to straighten everything that it just about fit the socket again but with more effort.
After doing so, the motherboard no longer registers any BIOS update pass 3.20.
It no longer recognises 128GB of RAM and only 64GB.
When i also placed my Ryzen 2600, similar behavior, can’t remember anymore (was too upset to keep in mind).
I may have completely bricked my Asrock x570 Pro4 and Ryzen 5950x.
Til now, I don’t have a working computer for (what I believe) over 5 months.
As @K4sum1 has already written, the Microcode modules for AMD CPUs are continuously developed, updated and released for the OEMs by AMD, but this does not mean, that all X570 chipset mainboard BIOSes contain the same Microcode versions. It depends on the motherboard manufacturer and the age of the mainboard whether and for how long the offered BIOS contains the latest available Microcode modules.

Yes I do recall, but I still thought it was definitely worth a shot, at least with these CPUs and motherboards I can conclude that it wasn’t a very good idea, unless there is someone who really know what they’re doing, best adviced to not go too much into it.
Anyway, I’ve moved on and now trying to get my newly repurchased 5950x working on another motherboard, Asus ROG x570-F.
Just can’t get passed the Starting Windows boot-up animation 
Use CSM and legacy boot.

As soon as I installed my motherboard, I ran BIOS setup and set it with CSM and Legacy mode.
Even after doing this, it still gives me this problem.
Also to note, it has no problem booting into Windows 10.
